ethanol is really bad, evinrude 88 6hp

[dkonrai]

my recent adventures on purchasing a 88 6hp longshaft evinrude. it ran and idled great, but, did not want to throttle up.

ended up that the throttle cam arm was broken a common item that breaks. replaced the cam then the motor still did want to throttle up. i didnt really want to pull the carb due to the recoil starter is a pita. pull the carb and primer. primer is closed due to carbon and this slimy fiber like stuff. it was all over and in the fuel system. the fuel pump was clogged as well. my assumption is the previous owner never ran seafoam or stabil. i have pulled at least 30 carbs apart and this was one of the worst i have seen. blew carb cleaner through every orifice, as well as small strands of wire.

ethanol is really some bad stuff. amazing this little motor ran at all. i know i paid way too much for the motor, 180.00 but its pretty clean on the inside and seems to be a low hour motor.

You need to be more choosy.

I run my 1990 9.9 hp every weeek for 20 weeks almost every day & use 6 gallons a week in it. Valero gas Hardware store oil. Leave some gas in the tank every winter NO stabilizer.


Always starts up with no haircuts needed. You sure that is / was gasoline ? Diesel can grow stuff.

the fuel pump had a bunch of slimy/carbon deposits as well as what looked like calcium on the check valves , spring, diaphram. the carb bowl had this slimy stringy goo stuck on the bottom of the carb bowl. the good is the plastic bowl and top are all ok and not cracked or warped. and no it wasnt diesel fuel. at least i dont think so.

Ethanol does not cause neglect and abuse. It just gets blamed for the results.

Re: ethanol is really bad, evinrude 88 6hp

Ethanol IS a VERY POWERFULL solvent. It should prevent what happened to your carb. The whitish deposits could be from a very old & watery load of gasoline the the boat had.

The boat / motor was badly abused after the last running.

That's about the best explanation I've seen yet.

We've had ethanol as an additive in gasoline for something like 25 or more years now, manufacturers have had plenty of time to figure out what materials are compatible with it (and as far as I can tell they've done so). It's amusing how many problems with boat engines get blamed on ethanol when there's no logical basis for doing so, I think ethanol is the boating worlds own little boogie monster that will never go away.

The only thing I hate about ethanol is the gas mileage in my vehicals has dropped since we've been forced to use the 10%. It sucks !!

be glad you dont live in cali. our gas is really bad, the bay area has its own formula. yes my truck and cars go through it rather quick. mileage has dropped 20%.

Well as far as ethenol goes my manuel for my 98 115 intruder says i can run e10 which is a acceptiable fuel but may cause performance issues , and it does cause some issues in hot weather so i started to buy non e10 at a marina performance issues gone i do all my own engine work by the book so i know its the ethenol that cause performance issues in hot weather.

I hate ethanol threads. Let's assume that you had 20% ethanol (you don't). And let's assume it had only 50% the energy content of gasoline (it has more). Then you could only attribute a 10% drop in volumetric fuel efficiency (per gallon mileage). There is NO way that there is anything being sold in CA anywhere that is causing you to get 20% less fuel mileage unless you were buying E85. It just isn't so. And without 3rd party, unbiased data, I won't believe a word of it. There is no big fuel bogey man. There just isn't. It is tightly regulated, and very high quality in all 50 states, especially California. Yes I know about oxygenates, find me any reliable, legitimate data and I will retract every word.

I wasn't going to wade into this again, but since QC waded in before me here goes. A while back I did the math, and E-10 has about 1-2% less energy content than non blended gasoline. And what that means is that you would get 1-2% less fuel mileage per gallon when using E-10 compared to non blended gas.

C'mon QC, sticking up for Big Oil?

Next I suppose you are going to tell us that the 250 Mile Per Gallon carburetors, that the Big Oil Companies bought up and are hiding (or destroyed ), don't exist either. :facepalm:

Re: ethanol is really bad, evinrude 88 6hp

It was called the Fish Carburator & used a preheater to better atomize the fuel in the carburator. Oil companies bought the patent from the person. Big public settlement.

Big gasoline quality issue is that lots of people are putting cheaper Kerosene in with the gasoline. If your gas smess like fresh paved roads.........Guess what..........Nothing is being done about the screwing we are getting. HUGE problem around the world. + or - 20 % mileage is real.

No point in arguing whether this carb is a myth or real. With the invention of the flux capacitor any real or imagined technological advance encompassed in the Fish Carburetor has been leapfrogged.

Adding a small amount of Kerosene would probably increase mileage. But I don't believe that is happening here, and I have never heard about it anywhere in the world. Please drop this Kerosene thing. Will not go anywhere but downhill.

That urban myth has been floating around just about forever. Wanna' know why I know it's merely a myth that this carburetor could produce untold gains in gas mileage? Patents expire 20 years after they are filed (it used to be 17 years after being issued). This carburetor myth has been making the rounds for WAY more than 20 years, which means that even if an oil company had bought the patent it would now be in the public domain and anyone could produce it who wanted to. If it were any good at all we'd be seeing them on every car rolling off the assembly line, which we don't. FURTHERMORE - thermodynamically it just isn't possible simply by a carburetor swap. There would need to be major advances in friction reduction, drag reduction, heat recovery, etc. etc. etc. to make major gains in efficiency.

edit to add: Now someone tell me what the heck this has to do with boats. :facepalm:
